Arrays in golang

Golang array syntax

var arr1 [3]int                                           //ARRAY syntax#1
	arr2 := [2]string{"Hello", "World"}                       //ARRAY syntax#2 (composite literal)(identifier:= type{values})
	arr3 := [...]int{12, 13, 14, 15, 16}                      //ARRAY syntax#3
	arr4 := [5][2]int{{0, 0}, {1, 2}, {2, 4}, {3, 6}, {4, 8}} //ARRAY syntax#4
	var arr5 [4][3]int					  //ARRAY syntax#4.1
	arr5[0] = [3]int{1, 2, 3}
	arr5[1] = [3]int{4, 5, 6}
	arr5[2] = [3]int{7, 8, 9}

	fmt.Println(arr1, arr2, arr3, arr4, arr5)

Go arrays

var a [10]int // declare an int array with length 10. Array length is part of the type!
a[3] = 42     // set elements
i := a[3]     // read elements

// declare and initialize
var a = [2]int{1, 2}
a := [2]int{1, 2} //shorthand
a := [...]int{1, 2} // elipsis -> Compiler figures out array length

Arrays in golang

// var numbers [5]int
numbers := [...]int{0, 0, 0, 0, 0}
